Application led October 21, 1911.

To all whom 'Lt may concern;

Be it known that I, FREDERICK SCHNEIDER,

A a citizen of the United States, and a resident of Fort Leavenworth, in the county of Leavenworth and State of Kansas, have invented a new and Improved Radiator, of which the following is a full, clear, and eX- act description.

Thev object of the invention is to provide a new and improved radiator, arranged to insure a rapidy circulation of the steam, water or other fluid heating medium employed under any desired pressure, to dispense with the use of air valves or vents and thus avoid leakage, to prevent the escape of bad air from the radiator into the room in which the radiator is located, and to prevent hammering.

For the purpose mentioned, use is made ofl a series of connected radiator sections, a supply valve, a distributing pipe connected with the said supply valve and extending through the radiator sections, excepting the last one, in which the distributing pipe terminates, t-he said distributing pipe having openings registering with the interior of the radiator sections, and a return How pipe eX- tending through the said distributing pipe and having one endopening into the last radiator section and having the other end terminating adjacent the said valve.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both views.

Figure 1 is a side elevat-ion of the radiator, parts being in section; and Fig. 2 is a transverse section of the same on the line 2k2 of Fig. 1.

The radiator is provided with end sections A, A and intermediate sections A2, and the said sections are connected with each other at their lower ends by the usual nipples B, and similar nipples B are employed for connecting the sections with each other at their upper ends. The first radiator section A is provided on its outer side with a reducing coupling C provided with a short pipe C having an enlarged head C2 forming a receptacle for water and connected by a couplingD with a supply valve E, of any approved construction, constructed rand con- Vof condensation to the valve E and -the valve E and to the nected by a pipe F with the steam or other heating medium supply.

Through the nipples B extends concentrically a distributing pipe G screwing at its .forward end into the pipe C of the reducing coupling C, and the other end of the distributing pipe G terminates in the last radiator section A, and this end is closed by a cap G. The distributing pipe G is providedwith the distributing openings G2 in the top opening into the interior of the sections A, A and A2, soV that the steam or other heating medium passing through the valve E and pipe C into the pipe G can pass from the latter by way of the openings G2 into the several sections A, A, A2.

Through the distributing pipe G extends a return liow pipe H for returning the water pipe F with a view to return the water to the boiler or other source of supply. The forward end H of the return flow pipe H is bent downward in the head C2 of the pipe C so as to be water sealed by the water standing in the head C2, as will be readily understood by reference to Fig. l, to prevent the steam or other heating medium from passing into the end H of the pipe H. The rear end of the return flow pipe H extends through the cap G so that the space between the pipes G and H is closed at the outer end. The end of the pipe H extending through the cap G opens into the end radiator section A, to permit the water ofcondensation to flow from this end section A through the pipe H into the head C2, and from the latter into pipe F to be returned tothe boiler. The return flow pipe H is preferably arranged eccentrically within the distributing pipe G near t-he bottom thereof, and sufficient space is left between the pipes G and H to permit a ready flow of the steam or other heating medium through the pipe G to pass from the latter by way of the openings 'G2 into the radiator sections. It will also be noticed that by arranging the return flow pipe H in the manner described, it is located as low as possible to keep the level of the water of condensation as low as possible in the lower portions of the radi ator sections. By sealing the inner end of the pipe H, steam is prevented from freely entering the radiator sections and there is caused a jetting of the steam from the perforations G2 of the pipe G, because the condensation of the steam due to radiated heat `maintains a lower pressure in the radiator than within the pipe.

The pipe G extends preferably concentrically through the nipples B andsuflicientallowV a free circulation of the air of con-` densation from one radiator section tothe other, the water finally being drained out of `the radiator from the last end radiator section A, as previously explained. The outer face of the lastradiator section A is provided opposite the cap G 4with a standard plug I, and similar plugs 1 and I2 are arranged on the outer acevof theend radiator sections A and A opposite the nipples B, so that convenient accesscan be had to the upper and lower portions of the radiator sections on unscrewing the said plugs I, I Vand I2. The end radiator Ysections A and Aare provided with the usual legs A3, and for radiators having many sections'one or more of the intermediate sections may be provided with such legs, the same as now practised.

By the arrangement described, the vheating medium is readily distributed in the several radiator sections irrespective of the pressure employed, and the air valves and vents are completely dispensed with to reduce leakage to a minimum and lhammering is prevented as means are provided for a free escape of the water of condensation. It will further be noticed that the reducing coupling C, the distributing pipe YG and the return tlow pipe H can be readily placed insteam radiators'as now constructed.

on removing the usual nipples at the bottom of the radiator sections, removing the air valve and plugging up thehole. VBy arranging the radiator as shown and described the individual parts can be readily taken to the room or Aother `place in which the Yradiator is to be used and the parts assembled there: VThe pipes G and vH arranged as described may also be introduced into vradiators as now constructed without removing 'the nipples by simply disconnecting atvalve and inserting connected pipes Gand H through the bushing with which the valveV is usually connected.

Having thus described my invention, VLl claim as new and desire to secure 'byLetters Patent: K
